Abstract:
The present investigation was undertaken with main objective to determine the effect of pre harvest phytosanitation spray on seed quality of soybean. The foundation seeds of soybean variety of Dsb-21 were used for of crop rising. The crop was grown and pre harvest phytosanitation spray was carried at 15 days before harvesting in Seed Technological Research (STR) experimental site of Seed Unit and laboratory experiments were conducted NSP and Department of seed Science and Technology, University of Agricultural Sciences Dharwad. The five different pesticides along with one control [P₁: Hexaconazole 5%SC (2ml/L), P₂: Carbendazim 50%WP (0.5g/L), P₃: Nativo 75% WG {Tebuconazole 50% + Trifloxystrobin 50%} (0.5g/L), P₄: Streptocycline (0.15g/L) + COC 50%WP (2.5g/L), P₅: Spinosad 45%SC (0.2ml/L), P₆: Control] were used as treatments. Among different pesticides, spraying with nativo showed highest germination percentage (89.92%) and highest seedling vigour indices {SVI-I=3302 & SVI-II=7609}. The lowest disease incidence in blotter paper method (15.33%) and agar plate method (3.33%) was found in nativo and streptocycline spray. Lowest insect damaged (3.08%) seeds were observed in nativo and spinosad pre harvest spray respectively.
